Change Description |
|
|
|
S28H |
This code change fixes the following problem which affects Ultra
320 mode of operation only: If for any reason drive becomes “Format
Corrupt” (i.e. format operation is interrupted), drive can not be
formatted again in Ultra 320 mode (it can be formatted in U160 or other
modes). |
|
|
S28F |
Non functional fixes for U320 adapters only. Code
fix to prevent entry into AIX error log during microcode download to a
drive that is attached to U320 RAID Adapter and configured as a RAID drive
(522 Bytes/ sector formatted drive).
Also, code change to enhance drive’s write
operation performance when attached to U320 adapters. |

Approximately 20 minutes if
drive is part of rootvg(using Diagnostics CD); Approximately 5 minutes/drive if
drive is not part of rootvg(using concurrent
diagnostics).

If the data returned in the "Part Number" field matches the one
listed above AND the "ROS Level and ID...." field of that data is
below "53323848", this microcode applies. If this
level is already installed then the "ROS Level and ID...." shows "53323848"
Note: Drive microcode level in “ROS Level and ID …” field is
displayed in Hex value of ASCII characters in VPD data. Each alpha-numeric
ASCII character converts to a 2-digit hex number. For example in VPD displayed
above, 53 Hex= ASCII character "S"; 32Hex= ASCII character "2";
38 Hex=ASCII character "8";
48 Hex=ASCII character "H", microcode level is "S28H". Also note that the
microcode level "S28H" is
displayed in “Z1” field.
At AIX command line, type:
Diag
Select "Task Selection" from diagnostics menu.
Select "PCI RAID Physical Disk Identify"
Select SCSI RAID Adapter (press enter, then F7 to Commit)
This will display the Vital Product Data for Physical
Disk drives attached to the RAID adapter.
===============================================================
a) Make a directory on an AIX system to receive the AIX
format file.
Enter: mkdir
/tmp/fwupdate
b) Transfer the AIX format file to /tmp/fwupdate
directory (using "Save as ...").
You'll see the filename is S28H.bin
c) Unpack the file by executing the instructions below.
Enter the commands:
cd /tmp/fwupdate
chmod +x S28H.bin
./S28H.bin
[Don't overlook the periods (.) in the above command.]
The directory S28H with microcode files listed in section 1.1 will be added
to /tmp/fwupdate.
d-Enter the following command to copy the microcode files to " /etc/microcode " directory :
cp /tmp/fwupdate/S28H/IC35L*
/etc/microcode
e- If transferring files to a different system using floppy diskettes, use
the following procedure to copy files to diskette
Note: Don't overlook the complete path of microcode files, AIX Diag microcode download will not work if files are not
copied with complete path onto the diskette. Enter the following
command to copy microcode file(s) onto a floppy diskette
ls /etc/microcode/ microcodefilename | backup -ivf /dev/rfd0
where microcodefilename is microcode file that
is needed, for example:
ls /etc/microcode/ IC35L01.44533030.53323848 | backup -ivf
/dev/rfd0
Note: The instructions that follow are specific AIX commands. AIX commands are CASE (lower and upper) SENSITIVE, and must be entered exactly as shown, including filenames.
a) Make a directory on an AIX
system to receive the RPM format file.
Enter: mkdir
/tmp/microcode
b) Transfer the RPM format file to
the /tmp/microcode directory (using "Save as
...").
You'll see the filename is 2104_ic35l-S28H.rpm
c) Unpack the file by executing the
instructions below:
Enter the commands:
rpm -ihv
–ignoreos 2104_ic35l-S28H.rpm
The file size and checksum will be verified.
The microcode files will be added
to /etc/microcode/
Copy microcode updates from the CD-ROM to standard locations on your local disk:
1. RPM packaged microcode files
will be copied to "/tmp/microcode/RPM"
2. Microcode files will be copied to /usr/lib/microcode
Notes:
- "/etc/microcode" is a symbolic link to "/usr/lib/microcode".
- If permission does not allow the copy to the above stated directory
or file then the user will be prompted for a new location.
========================================================
Warning: Do not power off the system or the drive during microcode download as this may permanently damage the disk drive
NOTE: Please save current and older versions of the microcode update files in case you need to restore your system.
Caution: The microcode download process is nondestructive to the hard disks; however, as a precaution, ensure that a backup operation has been performed on the affected systems PRIOR to the microcode installation.
Can microcode be installed Concurrently?
AIX level 5.1 and above supports concurrent microcode download on all drives,
including drives that are part of rootvg.
AIX level 4.33 and below does not support concurrent microcode download if
drive is part of rootvg, microcode download can ONLY
be performed in service mode(stand alone) using diagnostics CD. If disk is not
part of rootvg, microcode download can be performed cuncurrently as long as drive is not in use.
Is system reboot needed to activate the microcode: Yes if stand alone diagnostics is used, NO if concurrent diagnostics is used.
Installation Time: Approximately 20 minutes/drive if stand alone diagnostics is used(using Diagnostics CD); Approximately 5 minutes/drive if consurrent diagnostics is used.

be performed either from Diskette or from Disk. To copy files from the diskette
to disk, place the diskette containing microcode files into diskette drive A,
at AIX Prompt type restore
2- At AIX prompt, type diag
